Is a 360 watt power supply in a med tower ATX case enough for a Pentium IV 1.8 Ghz, 512 MB RAM, a 30GB HD, CPU fan, heatsink, 2 extra case fans, vid card, sound card etc? I have the choice of 320 watt, 360, or 400 but the 400 waould be a little above my budget. That's why I'm wondering if the 360 watt supply would be fine. And how do you know by the way how much power supply you need?
